Keywords: LungVolume.jpg Lungvolumes svg This is a prototypical output of a ' en spirometer' The vertical axis signifies the en volume and the horizontal axis signifies en time The bottom left corner equals zero lung volume at the start of the spirometer recording session The first small en amplitude part of the en sinusoid depicts repeated resting state involuntary breathing The amplitude of this small sinusoid corresponds to the 'Tidal Volume' The large positive amplitude spike represents voluntary inspiration to maximal volume or 'Total Lung Volume' The large negative amplitude spike represents forced expiration to the lowest possible en physiological lung volume called 'Residual Volume' All of the en lung volumes commonly referred to in the literature are labeled Vihsadas 21 31 18 April 2007 UTC Vihsadas talk 05 52 7 March 2008 UTC Vihsadas 20 10 14 April 2007 UTC Transferred from http //en wikipedia org en wikipedia 2007-04-13 Original uploader was Vihsadas at http //en wikipedia org en wikipedia Released into the public domain by the author LungVolume cs png Vihsadas en Being somewhat adept at nit-picking I noted that the graphic on Lung Volume shows VT for Tidal Volume Based on what I observe in the rest of the graphic that graphic element should be TV Certainly this is not a grievous error original upload log page en wikipedia LungVolume jpg 2007-04-18 21 43 Vihsadas 935×323×8 128701 bytes <nowiki>This is a prototypical output of a 'spirometer' The y-axis signifies the volume with the bottom left corner equaling 'zero volume' The sinusoid comes from repeated resting state breathing small amplitude sinusoid 'Tidal Volume' one inspiratory segme</nowiki> 2007-04-18 21 29 Vihsadas 935×323×8 128531 bytes ' 2007-04-13 01 06 Vihsadas 836×327×8 116712 bytes <nowiki>This image was UPDATED using the original image that was posted here Therefore it is fair usage There is no copyright holder The original owner of the image made the file and uploaded it here I updated it with new information Since it was already upl</nowiki> Respiratory system Physiologic diagrams Spirometry Amplitude |
